I have no idea how to calculate actual reaction-force of radiation vs. gravitation. I only notice its effect in the solar system, and surmise there must be relation between what we see near by and what we see far away. Think of Drake equation with many variables. You’re arguing with degree of influence of 2 or 3 of them. I shrug.
One of the variables, however, is star-formation rate, which is observed to be falling. As I understand Sylas' analysis, for exponential model to match data, H cannot be “constant,” but must fall by 6% (or something) per billion years, which is in the same neighborhood as drop-off in star-formation rate. It is
this prediction of DEILE that is within 1 OOM of observations, but more to my relief, at least in the right direction!
As for how all the other factors enter into calculation of H: that is what I am uncertain of to many OOMs. The influence of one variable—star formation rate—is in right direction and to within 1 OOM, but I have no idea if the sum-total influence of the many variables is correct within any number of OOMs.
